The network war nobody talks about: Ultra Ethernet vs InfiniBand.
UEC 1.0 launched June 2025. Open Ethernet now approaches InfiniBand performance.
Ultra Ethernet wins inference scale-out. InfiniBand holds frontier training (sub-1us latency, proven at 100K+ GPUs).
AI hardware refreshes under 5 years. Facilities that cannot support 3-ton racks or liquid cooling face obsolescence.

🚀 Ultra Ethernet: Built for AI-Driven Data Centers
AI workloads are pushing traditional Ethernet to its limits. Meet Ultra Ethernet—an emerging solution designed for the scale, speed, and precision that AI clusters demand.
In our latest blog, we break down:
🔹 Why legacy Ethernet falls short for AI
🔹 How Ultra Ethernet improves latency, congestion control & reliability
🔹 The role of the Ultra Ethernet Consortium (UEC)
🔹 What this means for hyperscalers and data center architects

Network utilization is very important in AI data center networks since it affects JCT and Inference Throughput. Caused to several factors, traditional Ethernet generally has a 35% to 40% utilisation rate. Ultra Ethernet boosts network utilization. Asterfusion unlocks the full potential of Ultra Ethernet utilization.
